Question

021-cm-diameter electrical wire at 32°C is covered by 0.05-cm-thick 05 plastic insulation (k = 0.13 W/m °C). The wire is exposed to a medium at 10°C, with a combined convection and radiation heat transfer coefficient of 14 W/m² C. Determine if the plastic insulation on the wire will increase or decrease heat transfer from the wire

Answer 1

Explanation:

A 0.21 cm diameter electric wire at 32°C is covered by 0.05 cm thick plastic insulation ... The Wire Is Exposed To Medium At 10°Сwith Heat Transfer Coefficient Of 14 W/m2-K. Determine If .
